For me it's Corner Gas. I still think it's pretty funny and there's a decent amount of references to Canadian stuff but not enough to be off-putting. I feel like an American wouldn't be confused watching it even if some of the references get a bit dated overtime.
I have only seen a bit of the animated version in waiting rooms.
Ahhh, Kids in the Hall is it.
I probably have seen some of the other stuff on TV at some point, but that and SCTV are all that come to mind, and SCTV I never saw back then, it was only after the internet that I finally saw some, so I don't know if it counts for what you're asking.
Kinda strange considering how many of the SCTV cast are on my list of favorite comedic actors.
